Question

The assimilatory power in photosynthesis is

• A. ATP
• B. NADPH
• C. ATP and NADPH${}_2$
• D. ATP, NADPH and CO${}_2$

Answer 1

The correct option is C ATP and NADPH${}_2$

Photosynthesis is an important physiological process that takes place in the chloroplast of the green plants wherein sugar is synthesized from water and carbon dioxide in the presence of light. This is also referred to as carbon assimilation reaction as this oxidation- reduction process involves a light reaction and dark reaction where water is oxidized and CO${}_2$ is reduced to carbohydrates. In light reaction, ATP and NADPH${}_2$ are produced and in the dark reaction, CO${}_2$ is reduced with the help of ATP and NADPH${}_2$ to produce glucose.

So, the correct answer is 'ATP and NADP$H_2$
